I've tried several ad spy tools, but BigSpy offers the best value for money. The database is massiveโespecially for Facebook and TikTok ads. It saves me hours of manual research and helps me spot trending products before the market gets saturated. If you run a dropshipping business or manage paid social, this is a non-negotiable part of the tech stack. Highly recommended for the "Ad Ideas" feature alone.
It has a huge database of ads on several social platforms, like Facebook, Instagram, Twitter, AdMob, Pinterest, and Yahoo, so we can check different ads for ads inspiration. Also, we can spy on competitors and track the performance of their ads to decide new marketing strategies.
While itโs still in early stage, its lifetime deal is really a great value. Must get if youโre into lead generation.
Based on our record, BigSpy seems to be more popular. It has been mentiond 1 time since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
